Patented Nov. 29, 1932 E-"CEE J'AM'ES .N. 'WHITE, F DENVER, COLORADOGYLINDER LAUNDRY MACHINE This invention relates to cylinder Ilaundrymachines and particul'arly 'to thatcl'ass thereof in which there is anouter cylindrical tub within which is revolubly mounteda cylin- 1 4drical clothes container.

An object of the invention is to provide improvements in the structureand operation thereof with relation to -the dumping of'the clothesfromthe machine after the clothes have been w'ashed'ordried within themachi me, it being understood-that while the' machineis here describedasa washing machine it cam-with appropriate additions not affect ing thefeatures involved in the present inventio'n, be as well usedfordryingclothes.

A further'obj'ect is toprovide'for the dumping o-f the clothesfrom-thenrachine by providing an outer cylindrical {tub constructed i'ina pluralityof sections means 'beingpro- 'vided for revolving thelower section when desired.

Afurthcr object is to 'provide a machine of the class describedcomprising an outer cylindricaltub made'in sectionsnormally stationeary, aninner'cylinder revoluble within the outer tub and means forcausing the lower sectionof the outer tub to revolve withthe innercylinder for dumping the clothes from theinnercylinder.

Other obj ectswill appear fromthe following specifications and claimsasillustrated in the accompanying drawings in which like characters"ofireference indicate correspond- .35 ing' parts throughout and inwhich Figure I is a-front elevation of a four compartment machineshowing the'left half of theitub open and dumping'bags attached to theopening in the inner cylinder-ready for the revolution oftheinnercylinder and lower section ofthc outer tub for the purpose ofdumping clothes from the inner cylinder, the right half ofthemachinebeing open as to both outert-ub and inner cylinder and the .15dumping bags being hung upon the racksin therposition indicated inthe-next figure.

to the fioor as indicated at 2-and which support suitable bearings 3 forshafts isuitably fastened to the ends Set the perforated inner cylinder6'whichmay be referred to as the container. Thecontainer is thereforerevolubly supported by means of theshafts 4 in'bearings 23in standards'1.- The normal revolution of the container 6 is accomplished by power"transmitted from any suitable source-to pulleys 7 ,=thence throughshaft 8 and thence through the series of encased cogs indicated at 9, 10and 11,'cog11 being-fixedly so that'the revolution of the cog 11revolves the container'ti.

The upper portion of the container6 is drical casing 12 which issupported andlthe ends'of'which are closed by the members 18 whichmay-be formed-integral withthebearingB as clearly shown in Fig. I.

Roller bearings11 are carried by the stand ards l and on these bearingsthere'are revo'lubly mounted rings 15 to which rings there is attachedby any suitable means an approximately semi-cylinder '16 forming the"lower portion ofthe outer tub or casing. 'Thering 15 isprovide d with arim'15a which overlaps the roller'bearing 14 and the-roller bearing 14is provided with a'rim 14a which over laps the ring '15andthe-semi-cylinder 16'is attached to the rim15a of each of the'rings15 which rings are-thereby maintained in desired relatively spacedrelation and the rims 14a and 15a serve to further maintain the rings 15and the semi-cylinder 16 in the thereto the rings 15 may revolve uponthe bearings 14, carrying the semi-cylinder 16 with them.

The semi-cylinder 16 is provided with a hollow rib 17 for theaccommodation of water inlet pipe 18 whereby water may be let in to thesemi-cylinder 16 when it is in normal position, a valve 19 beingprovided for this purpose in the pipe 18. A suitable drainage trap 20 isprovided which may be of any approved construction and is therefore notdescribed in detail.

Container 6 is provided with openings 21 for loading and unloading thecontainer and these openings are provided with doors 22 sliding inrunways 23 attached to the container 6 and the doors 21 are providedwith suitable handles 24.

The stationary semi-cylinder 12 is likewise provided with openings 25closable by doors 26 sliding in suitable runways 27 and provided withsuitable handles 28.

The machine is so constructed that the space therebeneath is open andunobstructed so that any desired receiving devices for the clothes to bedumped from the machine may be placed thereunder but as an improvedmethod of dumping the clothes from a machine of this character I providea rack 29 hingedly attached at 30 to the front edge of the semi-cylinder16, the rack being provided with the brace rod 31 pivotally mounted inthe outer end of the rack as at 32 and hav ing a suitable seat 33attached to semi-cylinder 16 for the other end of the brace rod wherebythe rack may be maintained in horizontal position as shown in Fig. IIand at the right of Fig. I for positioning the bags 34 prior to thedumping operation.

It will be understood that in loading the machine the doors 22 and 26 inthe container 6 and the semi-cylinder 12 respectively are open and theclothes are placed in the container and the doors are closed and theWashing or drying operation is performed with the revolving of thecontainer by the means above described. After the washing or dryingoperation is completed the racks 29 are positioned as shown in Fig. IIand the bags 34 are positioned therein and the doors 22 and 26 are againopened whereupon the racks 29 are swung into the openings 21 in thecontainer 6, the openings of the bag being of the same size as theopenings 21 and being positioned in the rack 29 so that they will fit into the openings 21 as clearly shown at Fig. III, lugs 35 being providedfor catching under the handles 24 to hold the racks 29 in position withthe openings of the bags in the openings 21 ready to receive the clothesfrom the container 6. When the rack 29 has been swung in to thisposition the brace rod 31 falls to a position parallel with the rack 29as clearly shown in Fig. III and suitable means as catch 36 are providedfor engaging the brace rod and holding it in this position parallel tothe rack 29 during the dumping operation. When the bags have been thuspositioned the semi-cylinder 16 with the dumping bags is locked to thecontainer 6 and revolved therewith for dumping the clothes, the lockingand revolution being accomplished by the means new described.

Various means may be used for causing the container 6 and thesemi-cylinder 16 to revolve from position shown at the left in Fig. I tothe dumping position shown at Fig. III but I have illustrated as aconvenient and suitable means a ring 37 carried by the ring 15 andhaving an annular groove 38 forming a channel for finger 39 when ring 37revolves as hereinafter described. Sleeve 40 is carried by ring 37 andwithin this sleeve is slidably mounted the lock pin 41 having a hookedportion 42 slidably lying in the channel 43 formed by cutting away asection of ring 37.

When semi-cylinder 16 is in normal posi tion as in Fig. I the hook 42 ofpin 41 lies directly beneath finger 39 so that the finger fits into thehook and the movement of the finger to left or right by revolution ofthe rod 44 on which the finger is fixedly mounted will slide the lockingpin to left or right as the case may be.

In Fig. I finger 39 is shown as swung to the left having slid pin 41 toits limit of movement in that direction and in this position the ring 37cannot revolve because of the posi tion of finger 39 in channel 43. Inthis posi tion therefore the rin s 37 and 15 and semicylinder 16 areheld against revolution. When rod 44 is revolved to swing finger 39 tothe right the finger, operating in hook 42 slides pin 41 to the rightuntil the hook 42 is aligned with channel 38 rendering the chan nel 38continuous or a complete annular channel for finger 39 as ring 37 isrevolved.

When pin 41 is slid to the right as last described, its shank protrudesfrom sleeve 40 into a hole 11a in the frame of cog wheel 11 thusinterlocking ring 37 with its attached ring 15 and semi-cylinder 16 tocog 11 and the container 6 through shaft 4, whereupon cog 11 may berevolved by any suitable means worm 45 turned by wheel 46. Through theinterlocking above described the revolution of cog 11 causes container 6and semi-cylinder 16 to revolve together to the position wherein bags 34are at the bottom as indicated at Fig. III in which position the clotheswill fall from the container into the bags. It will be understood thatthe last mentioned revolution may be continued beyond position shown atFig. III if necessary in order to dump clothes which stick on the sidesof container 6.

The finger 39 is moved to ri ht or left by revolution of shaft 44 andshaft 44 is revolved by weighted arm 47 carried by sleeve 48 mounted onshaft 44 and having lugs 49 adapted to engage lugs 50 on sleeve 51 inwhich shaft 4:4: is revolubly mounted, sleeve 51 being supported in anysuitable manner as by member 51a a fragment of which is shown at Fig. V.

The weight 52 on arm 47, acting through shaft 44, holds finger 39, andwith it the pin 4-1, in extreme position to right, permitting revolutionof ring 37 with cog 11, or to left, withdrawing pin 41 from cog 11 andlocking the ring 37 against revolution, as the case may be.

Many parts and constructions herein described may be changed to thosewhich are standard and/or commonly employed in this art or to anymechanical equivalent, and other changes in structure may be made,without affecting the spirit or substance of this invention and withinthe scope of the claims.
